Tensor Perturbations in Anisotropically Curved Cosmologies

, 2017
Besides expanding anisotropically, the universe can also be anisotropic at the level of its (spatial) curvature. In particular, models with anisotropic curvature and isotropic expansion leads both to a $\Lambda$CDM-like phenomenology and to an isotropic ...

Feasibility of Deep Learning in Shear Wave Splitting analysis using Synthetic-Data Training and Waveform Deconvolution

Seismica
Teleseismic shear-wave splitting analyses are often performed by reversing the splitting process through the application of frequency- or time-domain operations aimed at minimizing the transverse-component energy of waveforms.

Systematic bias in shear-wave splitting measurement

Geophysical Journal International
SUMMARY Shear-wave splitting measurement returns two parameters related to the fabric of the upper mantle: the orientation of the fast polarization (fast direction), and a measure of the intensity and thickness of the fabric known as the split time. Spatial statistics of compiled splitting measurements indicate that the fast direction

Nucleon Effective Masses in Neutron-Rich Matter

, 2018
Various kinds of isovector nucleon effective masses are used in the literature to characterize the momentum/energy dependence of the nucleon symmetry potential or self-energy due to the space/time non-locality of the underlying isovector strong ...

Calculation of shock-separated turbulent boundary layers [PDF]

Numerical solutions of the complete, time-averaged conservation equations using several eddy-viscosity models for the Reynolds shear stress to close the equations are compared with experimental measurements in a compressible, turbulent separated flow. An

Shear-wave attenuation anisotropy: a new constraint on mantle melt near the Main Ethiopian Rift

Seismica
The behaviour of fluids in preferentially aligned fractures plays an important role in a range of dynamic processes within the Earth. In the near-surface, understanding systems of fluid-filled fractures is crucial for applications such as geothermal ...

Anisotropy and Energy Evolution Characteristics of Shales: A Case Study of the Longmaxi Formation in Southern Sichuan Basin, China

Geofluids
To obtain the influence of anisotropy and energy evolution characteristics on wellbore stability, the acoustic and mechanical anisotropy characteristics of shales are studied through various experiments, including scanning electron microscopy, ultrasonic

Progress in mantle anisotropy research based on XKS phases

地球与行星物理论评
XKS shear-wave splitting has been widely applied to investigations of anisotropy in both the upper mantle and the lowermost mantle D" layer, and represents a key tool for probing mantle deformation and dynamics.
